Hi Ulf,
This patchset consolidates polling for busy by using mmc_poll_for_busy()
to avoid re-invent the wheel for other code block. The only leftover is
mmc_test which not just poll for busy but also check if the host drivers
abuse MMC_CAP_WAIT_WHILE_BUSY.
V3 is rebased on top and the final one patch restores the throttle of
calling to MMC_SEND_STATUS during mmc_do_erase() and accessing RPMB.
Then it goes a little further for trying to improve the responsiveness
once only one CPU is online.
Changes in v3:
- rebase
- remove mmc_host_is_spi() from mmc_blk_card_busy() as
mmc_poll_for_busy() has considered it.
Changes in v2:
- remove goto label
- improve the patch sequence and fold in all related changes to make
the patch look better.
